ABSTRACT:
A device that prevents the unauthorized removal of a retainer pin that is slideably disposed within a bore which is collectively defined by a plurality of bores formed in the doors or windows to be locked, or frames therefor, when the same are fully closed. The device is a flat, elongate member having a transverse bend formed therein so that the device provides an inclined wall portion that projects at an angular relation to a base portion thereof. The inclined wall is apertured to receive the retainer pin and the edges of the aperture frictionally engage the pin so that it can not be removed from the bore within which it is disposed in the absence of a transient deformation of the inclined wall which decreases the angle between the inclined wall portion and the base portion of the device, thereby causing the edges of the aperture to release the pin.
